Lifetime measurements of helium-like and lithium-like oxygen

A high resolution Bragg crystal spectrometer has been used to measure the decay times of the transitions: 1s 2 – 1s 2p (1 1S–2 3P) and 1s 2–1s 2s 2p (1 2S–2 4P). They are 1.47 ± 0.08 and 3.48 ± 0.08 ns, respectively. Delayed decay has been observed from states with much shorter lifetimes. These resu...

Description
Summary:A high resolution Bragg crystal spectrometer has been used to measure the decay times of the transitions: 1s 2 – 1s 2p (1 1S–2 3P) and 1s 2–1s 2s 2p (1 2S–2 4P). They are 1.47 ± 0.08 and 3.48 ± 0.08 ns, respectively. Delayed decay has been observed from states with much shorter lifetimes. These result in non-linear curves on a semilogarithmic graph that are all similar to each other. Thus, more than one delayed decay contributes to the formation of these states.
